RSSI Monitoring Interface
The RSSI voltage is a function of the signal strength at the receiver and is used to measure the received
signal strength. RSSI varies from approximately 0 to 5 VDC. An RSSI calibration sheet is shipped with the
system to provide the installer a cross-reference between actual received signal level (in dBm) and RSSI
voltage. This sheet is useful for verifying link budget calculations and ensuring proper equipment
installation.

Front Panel LEDs
With the TRACER 6200 powered-on, the front panel LEDs provide visual information about the status of
the TRACER system. Table 2 provides detailed information about the LEDs.
the TRACER system. Table 2 provides detailed information about the LEDs.
AUX RS232 Interface (RJ-45)
The
AUX RS232
interface provides a female RJ-45 terminal connection (wired as a DCE interface), which
is used for a 9600 bps point-to-point connection between the local and remote systems (over the RF link).

Indicates that...
PWR
Green (solid)
the system is connected to a power source.
Off
the system is not currently powered up.
TST
Amber (flashes once)
power-up self-test is in progress. If the LED continuously flashes
or remains on (solid) after 10 seconds, the unit has failed
self-test.
or remains on (solid) after 10 seconds, the unit has failed
self-test.
STATUS
MOD1 and MOD2
Green
the module in installed and functioning properly.
Red (solid)
a port on the installed module is currently in alarm.
Off
no module occupies the slot.
PLAN A
Green (solid)
the system is transmitting on Frequency Plan A.
Off
the system is not transmitting on Frequency Plan A.
PLAN B
Green (solid)
the system is transmitting on Frequency Plan B.
Off
the system is not transmitting on Frequency Plan B.
RF LOW
Red (solid)
the RSSI level is below suggested minimum threshold
(approximately 10 dBm above the minimum receive sensitivity).
(approximately 10 dBm above the minimum receive sensitivity).
RF DWN
Red (solid)
there is a communication problem between the local and remote
systems.
